How we handle TR19 inspection in South Oxhey
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Those are minimums, and grease readings help set the real interval. Common call-outs are for sites with gaps in their extract records and an insurer’s request for a TR19 audit, on pre-clean surveys, insurer audits and wet film thickness tests.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in South Oxhey, that usually means a longer system to clean and more access panels to plan around.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Kitchen extracts in South Oxhey
Food Standards Agency records list about 64 cafés, restaurants and staff canteens and about 22 takeaways and sandwich shops across South Oxhey and its immediate surroundings (about a mile and a half). A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. The fire and rescue service for South Oxhey is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. London jobs normally start after the last service, with loading and roof access agreed with the building first.
Healthcare kitchens, like those at hospitals such as Northwood and Pinner Cottage Hospital (about 1.5 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands. For kitchens close to Carpenders Park station, where the day often starts early and ends late, the extract can be cleaned overnight.

South Oxhey questions
Can the work in South Oxhey be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in South Oxhey keeps running as normal. Tell us your opening hours when you ask for a quote.
Who inspects food businesses in South Oxhey?
Kitchens in South Oxhey are inspected by Three Rivers council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
How much does TR19 inspection cost in South Oxhey?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

What else we do in South Oxhey
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What the work involves, part by part
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes around an hour or two per canopy and duct system, and we clear up before we go. A name and number for whoever controls access to the building in South Oxhey saves time on the night.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- We report back with readings and a fixed quote.
Before we arrive
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.

Keeping the system healthy
So the system stays in good health:
- Have the latest report ready for insurance renewals
- Do not box in or cover duct access panels
- Flag oily drips near the extract
- Wipe the canopy surfaces regularly
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.
What affects the cost of TR19 inspection
You will get a fixed price before any work starts. It’s based on:
- Site rules, permits and inductions
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- The scale of the work
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.
Asking for a quote
There’s no need for technical detail. Just send:
- Detail shots of panels, filters and grilles
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To get a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Why deal with it now?
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. London sites work long hours, and the longer a job is left, the bigger it gets.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What we are called out for in South Oxhey
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
What we are most often called out for:
- Systems cleaned on a calendar with no measurements
- Sites with gaps in their extract records
- Cleaning intervals that may not suit the kitchen
- Insurers asking for TR19 evidence
Volunteers running a hall kitchen near Oxhey Chapel, or anywhere in South Oxhey, may not know when the extract was last cleaned, and a grease test settles it.
